⛔️ As a semi-aquatic plant, water mint can sometimes be found growing submerged in rivers and streams and this means there is a possibility of it containing Liver Fluke, a water-based parasite that can make us rather unwell. This is especially so if cattle or sheep graze nearby.

βœ… Harvesting submerged aquatic plants for eating is ok, as long as you cook or steep the plant in boiling water before consuming. This kills any water-bourne parasites so they can't infect you. Collecting from fast-flowing water (i.e. not stagnant pools), and harvesting the plants above the waterline is also good practice. Watermint and other aquatic plants can often be found on land near to water as well, rather than submerged, and these are perfectly safe to consume raw.
